Jouberton, North WestAges 2–5 - NCT05602610Recruiting
Predicting relapse risk after visceral leishmaniasis
This study looks at a prognostic score to predict whether visceral leishmaniasis (VL) will come back after treatment. If you qualify, your information may help doctors estimate relapse risk and plan follow-up more safely.
GonderAges 12 years+ - NCT03895593Recruiting
Fecal transplant for stubborn intestinal infections
This study looks at “rescue” fecal microbiota transplantation (FMT), which replaces gut microbes using stool from a screened donor, for intestinal infections that have not improved with standard care. It may help patients whose infection keeps coming back or doesn’t respond to treatment.
Nanjing, JiangsuAges Any age - NCT04231565Recruiting
Testing antiviral medicines for hepatitis B with normal liver blood tests
This trial studies how well nucleoside (nucleoside-acid) type antiviral medicines control hepatitis B in people whose liver enzyme test (ALT) is currently normal. It may help those with active hepatitis B but no major liver inflammation on recent bloodwork.
Guangzhou, GuangdongAges 18–65 - NCT06289270Recruiting
Bladder cancer and urine bacteria study
This study looks at bacteria in urine and the bladder to understand if they play a role in causing bladder cancer. Researchers will compare samples from men with bladder cancer and healthy controls.
Cairo, Giza GovernorateAges 18 years+ - NCT04443179Recruiting
Baby brain scans in England to study early development
This study does brain imaging (brain scans) in babies to better understand early brain development and how factors like family history and COVID-19 might relate to development. It may help researchers learn which babies could need extra support later.
LondonAges 16–75 - NCT06289660Recruiting
Italian study on tuberculosis in children
This study follows children and teens with different stages of tuberculosis (TB) across Italy. It aims to learn more about how TB affects young people and improve care.

Iodine rinse vs salt water rinse in planned colon surgery
This study compares using povidone-iodine (an iodine-based cleaner) versus saline (salt water) to rinse the surgical area during planned colon or rectal surgery. The goal is to see which helps prevent infections at the surgery site after the operation.
Porto Alegre, Rio Grande do SulAges 18 years+ - NCT05789901Recruiting
Using a Facebook chatbot to share health information
This study tests whether a Facebook Messenger chatbot can provide helpful health information for different conditions. You may help researchers check if people can use the chatbot and understand the information.
Montreal, QuebecAges 14 years+ - NCT05979545RecruitingPhase 4
Early treatment with ceftazidime-avibactam for serious infections
This study tests an antibiotic called ceftazidime-avibactam for people with serious infections like bloodstream infections or pneumonia that started in the hospital or from a breathing machine. It aims to start treatment quickly after identifying the bacteria.
Kuala LumpurAges Any age - NCT06307171Recruiting
Leishmaniasis: studying the body's immune response
This study looks at how the immune system reacts to Leishmania infection and searches for new ways to diagnose the disease. It may help develop better tests for leishmaniasis.
Negrar, VeronaAges 18 years+ - NCT05688774Recruiting
Study of worsening community pneumonia in people with weaker immunity
This study follows how community-acquired pneumonia progresses in hospitalized patients who already have serious health problems or weakened immune systems. The goal is to better understand risk and changes over time, which may help guide future care for people like you.
